v2 new feature - Sessions

Save Session: Saves the current state of all variables and
arrays of data in a binary file. This is given the same name as the
currently defined Output file but with the extension *.BIN. The
command is initially disabled but is enabled once any significant data
is entered. Save Session should normally be used just before Exiting
from MIDUSS.

Load Session: Restores the value of all variables and data
arrays from a specified binary file. Any data entered manually before
this point will be overwritten. For this reason Load Session is
usually used at the start of a design session immediately after
selecting the units.
